Plumb Lyra Teal

Latin plumbum, lead — referring to the lead-weighted plumb-line of pre-modern carpentry. As a color modifier, plumb implies a clear-and-vertical-true quality where the hue carries the visual register of gravity-aligned-and-perfectly-vertical surface. Sits at the crisp-and-balanced end of the grid, parallel to level and squared in usage.

Greek λύρα, lyre-of-Orpheus. As a color modifier, lyra implies a small-summer-constellation-and-Orpheus-lyre quality, the visual register of summer-Lyra-and-Orpheus-lyre hand-small-summer-constellation-and-Orpheus-lyre summer-Lyra-and-Orpheus-lyre-and-Bortle-1-sky lyra-and-small-summer-constellation-and-Orpheus-lyre surfaces under summer-Lyra-and-Orpheus-lyre-and-Bortle-1-sky July-and-August-summer-zenith ring-nebula-and-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to vega and cygnus in usage.

Anas crecca, the small dabbling duck whose male in breeding plumage sports a chestnut head crossed by a glossy green-blue stripe. The color refers to that stripe — the iridescent panel just behind the eye: a saturated, slightly muted blue-green with the optical depth of structural color rather than pigment. Cooler than cypress, warmer than cerulean, with the ornithological specificity of a color named for one feather of one bird.
